Method and system for timed split charging processing

Abstract

An embodiment of the invention discloses a method and a system for timed split charging processing. The method comprises the following steps that an IMS (IP Multimedia Subsystem) network element transmits a charging beginning message to a CCF (Charging Collection Function) unit; the CCF unit returns a charging beginning response message to the IMS network element, and the charging beginning response message comprises a preset timed split time interval value; the IMS network element starts a timed split timer according to the timed split time interval value, the start time for establishing a call session is taken as the starting time, and timing is carried out according to the timed split time interval value in sequence; when the end time corresponding to the timed split time interval value is up at each time, the IMS network element generates a charging middle message according to a session call status of a call service and transmits the charging middle message to the CCF unit, wherein the charging middle message comprises a timed split mode identifier; and the CCF unit synthesizes charging messages which do not generate a ticket in the session according to the timed split mode identifier so as to generate a timed split ticket. According to the embodiment of the invention, charging accuracy of the timed split ticket generated by the CCF unit in the IMS network can be implemented.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and system for timing division billing processing. Background technique [0002] Internet protocol (IP) multimedia subsystem (IP Multimedia Subsystem, IMS) network, as the core network architecture of multi-service integration, provides a platform for fixed network and mobile network to realize all-IP network integration, in which voice and video call sessions are Service is the basic service of IMS, and it is also an important basis for building richer multimedia convergence services. For call session services, in order to avoid billing losses caused by failure to generate bills in time during long calls, the network is required to provide the function of generating timed split bills for long calls. In traditional networks, call bills for session services are directly generated by network elements that provide services, and the network elements generate timing split bills ac...

Problems solved by technology

[0007] The main reason for the above problems is that the time point of triggering timing segmentation in the above method comes from the CCF, but the relevant session status information in the bill comes from the IMS network element. However, the timing point of triggering timing segmentation is closely related to the session status. Only based on the CCF unit's own time, it is impossible to obtain the conversation status corresponding to the time point
